Hello there,
I would like to introduce these OpenSprinkler Addon that based on https://opensprinklershop.de modded firmware. The main difference that is support Analog sensor API. that mean it possible to add for example MQTT based sensors. More info: Activate analog sensor configuration – OpenSprinklerShop
The addon also working on amd64 and armv7 architecture. The program are compiled on OSPI mode, so it support https://openthings.io Cloud access.
Feel free to test it! If you found problem, please report it!
Thanks!
